Berdly's mom is a scientist of sorts.
my evidence: in the undertale 10th anniversary stream, one of the exclusive pieces of content is the hotland school area . one of the teachers there is a blue bird-like monster not quite dissimilar to everyone's favorite little nerd.
one might think this a funny little reference, since a younger noelle can also be seen in snowdin along with probably at least one other subtle deltarune references sorry I forgot . but if you think about it, if you accept that this is berdly's mom in undertale, what does this say about in deltarune?
so my first conclusion is that, since Alphys is a scientist in undertale and a teacher in deltarune, if motherdly is a teacher in undertale she might be scientist in deltarune . I admit this is a little flimsy but I don't see why not . I also don't see how this could mean anything. but if I end up being right that would be cool.
I um don't really know where I'm going with this anymore so I'll just add, none of the characters in both undertale and deltarune exist in a vacuum, the only real differences between one and the other are their experiences. and also a little bit of time

I'm really tired i don't think i can finish writing this sorry bye

@sierra actually my favourite little nerd is you
